3. The Epic wasn't as good as some people would have liked. It wasn't as interactive as previous years and some people thought it was too easy or too boring.
Also, as an honourable mention, I'll add 4. The lights went off at midnight in the middle of the Epic due to an automatic timer that wasn't shut off and no one was able to get them turned back on so a bunch of people just gave up and left in the middle of the game.
Most of the issues weren't really Baldman's fault. But people have grown to expect a level of showmanship mostly created by WOTC in the past that was missing this year. I gather that Baldman expected WOTC to donate books as prizes for the All-Access pass people and WOTC changed their schedule to released their books too late to come out at Gen Con, leaving them without anything to give out.
I was pretty bummed by my epic experience, and was there when the lights went out. It was my understanding that the game was over though. Now you are making me afraid that my DM was so out of sync (poor guy just got tossed into the deep end) that I missed something.
